Ukraine hits two oil refineries deep in Russian territory

Ukraine said it has hit two oil refineries in multiple strikes deep inside Russia with patrol boats and other vessels in the Black Sea also hit.

President Volodymyr Zelensky said the Bashneft-Novoil and Slavneft-Yanos refineries were struck in the attacks aimed at limiting oil revenues Moscow "uses to finance" its war.

Yaroslavl regional governor Mikhail Evraev said Slavneft-Yanos was on fire after what he called the "largest enemy drone attack". He said four people were injured.

Meanwhile, Ukraine said at least 11 people were killed in Russian attacks, and the southern city of Kherson reported a total blackout. Russia said it targeted fuel, energy and transport facilities.

After deadly Kyiv strike, Ukraine warns interceptor shortage is costing lives

Both Russia and Ukraine have in recent weeks intensified attacks on major cities, energy facilities and warehouses, as the vast front line remains virtually static and all mediation efforts to end the war have brought no breakthrough.

Russian President Vladimir Putin launched a full-scale invasion of Ukraine in February 2022.

Zelensky said on Thursday that the struck Bashneft-Novoil refinery in Russia's Bashkortostan republic was about 1,300km (808 miles) from the Ukrainian border, whereas Slavneft-Yanos was almost 700km (435 miles) away.
